Pumps, Wells, Tanks, Controls / I'd like to optimize my well water system...help needed.
« on: November 29, 2021, 09:54:37 PM »
I have several questions but would basically like to optimize my well water system. I'm not happy with the current setup and I'm looking for solutions once I have a better understanding of how it could be improved.
My current setup:
We had our house built 3 years ago and the well guy put in a Goulds 25GS30 in a 4" well with a CSV2W. I then have a 1-1/4" sch 40 PVC from the CSV to a tee for a spigot. The CSV and spigot are about 1 foot apart. The 1-1/4" pipe continues a foot or 2 then tees again for a 1-1/2" irrigation mainline. The 1-1/4" pipe then continues to run to the crawl space where the pressure gauge and 50 gallon bladder tank are located for easy access. The PVC pipe then comes out of the bladder tank and converts to PEX to supply the house fixtures with water.
I think I remember my depth to water is 160' but I texted my well guy and he seems to think it is a little less than that. Either way I should be getting something like 25 to 28 GPM max at 60 PSI. The pump is about 350 ft deep from what I remember.
I have a large lawn thus a large irrigation system. I have 7 zones that require 22 to 28 GPM (may need to double check these numbers tomorrow). I also have a large drip irrigation system that supplies water to 30 large recently transplanted trees (15 to 30 feet tall trees). My pressure switch is currently set to cycle my pump between 45 and 70 PSI.
My problem is my pump cycles between 45 and 70 PSI every time we use water except when the 7 lawn sprinkler zones are operating. When they are operating we do get constant pressure although the pressure differs with each zone. ie Zone 2 may run at 50 PSI and zone 7 may run at 65 PSI, etc. They all run at different pressures. I would like them to run on the higher end pressure wise since each head runs optimally at 45PSI and that is difficult to get with the pressure drops I have in the irrigation system. ie. if the well is at a constant 65PSI I can maintain roughly 45 PSI at the irrigation heads but if the well is at a constant 50 PSI it is more difficult to get 45 PSI at the irrigation heads. This has forced me to move heads to different zones or find other ways to reduce the pressure drop in the pipe, valves etc.
I would prefer the system run at say 65 PSI when the house fixtures are being used, when the drip irrigation is being used, and when all lawn zones are being used.
I'm guessing the well guy installed the wrong CSV since the CSV2W requires 5GPM. I'm guessing that is the main problem.
Should the irrigation zones currently be operating at different constant pressures ie. Zone 2 runs at 50 PSI and Zone 7 runs at 65 PSI? Is it ok to have the spigot tee and the irrigation mainline tee between the CSV and the bladder tank? What changes in my system do you recommend?
Thanks for all your help! I'm sure I'll have more questions as you try to help with a solution.
